Background: LncRNA is a kind of non-coding RNA and its research is more popular in recent
years, which has more than 200 nucleotides. It plays a significant part in various biological functions, including
chromosome modification, genome modification, transcriptional activation, transcriptional interference, and
other processes. FTX, at the center of the X chromosome inactivation and it has been shown that lncRNA FTX
regulates cancer cells’ development, migration, and invasion in many studies.
Methods: Relevant literature was collected through the PubMed system search and is summarized in this article.
Results: LncRNA FTX abnormally increased in tumor cells, such as liver cancer, stomach cancer, leukemia, renal
cell carcinoma, colorectal cancer, glioma, osteosarcoma, etc. However, the expression level decreased in
temporal lobe epilepsy, liver cirrhosis, heart failure, etc.
Conclusion: FTX may be an important regulatory factor and a potential therapeutic target in cancers.
